# Overview

Cloud Notes Platform is a modern cloud-native notes management web application developed using containerized deployment architecture and public cloud infrastructure.

The application allows users to:
- create notes
- store notes persistently
- manage lightweight note workflows
- access the application securely over HTTPS

The system is designed using a multi-component architecture consisting of:
- Flask backend application
- PostgreSQL database
- NGINX reverse proxy

The application is deployed on an AWS EC2 virtual machine using Docker Compose orchestration and HTTPS reverse proxy configuration.

The project demonstrates practical cloud deployment concepts including:
- containerization
- reverse proxy configuration
- persistent storage
- automated deployment
- cloud-hosted infrastructure
- HTTPS certificate management
- environment-based configuration
